RADIATOR.

SPECIFICATION forming part of Letters Patent No. 563,029, dated J' une30', 1896.

- Application filed August 26,1891.

To all whom t may concern;

Be it known that I, BARRENT W. FELT- HOUSEN, of Milwaukee, in the countyof Milwaukee and State of IVisconsin, have invented certain new anduseful Improvements in Radiators; and I do hereby declare that thefollowing is a full, clear, and exact' description of the invention,which will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, andto the letters of reference marked thereon, which form a part of thisspecification.

The main object of my invention is to produce a cheaper and betterarticle than has heretofore been placed upon the market in this class ofdevices.

It consists of certain peculiarities in the construction of theradiator-sections proper and of the means for assembling and connectingthe same.

In the accompanying drawings like letters designate the same parts inthe several iigures.

Figure lis an edge elevation of a number of sections, showing the mannerin which they are assembled in a radiator. Fig. 2 is a horizontalsection, on an enlarged scale, of two connected sections. Fig. 3 is avertical medial section of a portion of a radiator-section. Fig. 4 is aside elevation of the same, and Fig. 5 is an axial section of one of theconnections or couplings.

A A represent radiator-sections, which may be constructed of varioussizes and shapes, each composed of two metallic plates B and C, whichhave corresponding continuous grooves or channels impressed or formed intheir adjacent faces, so that when the plates are placed together acontinuous steam conduit or passage c a is produced. The plates of whicheach radiator-section is composed are secured together by extending theouter edge b of one section, B, beyond the edge of the other section, C,and folding it over the same in the manner shown most clearly. in Figs.2 and 3. The plates are secured together inside of the channel o,preferably along the central line of the section, by forming flangedeyelets b' in one section, B, and inserting them through Serial No.403,787. (No model.)

corresponding perforations in the other section, C, and upsetting themover it.

Each section is provided at its lower side or end with lateral openings,one constituting the inlet and the other the outlet of the passage d,and with screw-threaded couplings D and E, by which the sections arecoupled together and connected with the steam supply and return pipes.These couplings are preferably made of malleable or cast wro ughtiron,Iianged as shown in Figs. 3 and\5, for attachment to the edges of theplates composing the radiator-sections around the openings in which theyare placed. The coupling D on one side of each section is externallyscrew-threaded and projects outwardly. It is formed with flanges d d',which are upset and snugly clasped overl the edge of the plate aroundthe opening in which it is inserted. The other coupling, E, isinternally screwthreaded to receive the coupling D, and projectsinwardly into the passage d in line with said coupling D. It is alsoprovided with anges e c', which are upset and clasped in like mannerover the edges of the plate around the opening in which it is inserted.

Then the parts of each section hereinbe-- fore described have beenassembled in the manner specified, the section is placed in a bath andgalvanized or plated, the component parts having been previouslygalvanized, tinned, or plated to insure the metal working into andfilling the joints in the subsequent operation. By this means all thejoints are sealed and any possibility of leakage is avoided. Theconstruction described, by which each section with its couplings isproduced complete before the sections are assembled, greatly facilitatesgalvanizing the sections, inasmuch as the operation can be performed bythe employment of a much smaller bath than is necessary where thesections are assembled and it is necessary to immerse the entireradiator to insure perfectly tight joints in the connections between thesections.

By my construction and arrangement of the coupling devices any number ofsections may be connected directly with each other by screwing the malecoupling D of one'section IOO into the female coupling E of the adjacentsection, and so on. The outer couplings of the end sections afford meansfor the attachment of the ordinary steam pipes or connections. Aperfectly tight joint is secured between the sections by simply screwingone member of the coupling tightly into the other, and galvanizing orother means of sealing the connecting-joints is thus renderedunnecessary.

It is obvious that the steam-passage a may be made of various forms incross-section, and that the shape and dimensions of the sections may bevariously changed within the scope of my invention. The eyelets by whichthe component plates of the sections are secured together inside of thesteam-passage a also afford means for bracing and securing the sectionsat the desired distances apart. For this purpose one or more rods F arepassed through, the eyelets which come in line in the sections, andtubes or sleeves f f, cut or formed to the desired length, are placedthereon between the several sections, so as to bear at their endsagainst opposite sides of the sections and hold the same in their properrelative positions, as shown in Fig. l. The end sections are held inplace on their outer sides by a head and a nut or two nuts on said rod.

In a one-pipe system the outside coupling on one of the endradiator-sections may obviously be dispensed with,

I claiml. A radiator-section composed of two plates of sheet metal withcorresponding grooves or channels in their adjoining faces forming anendless tubular passage, said plates being joined together at the outerside of said passage by the edge of one being folded over the edge ofthe other and at the inner side where the plates come together byeyelets formed in one of the plates and inserted through and folded overthe edges of corresponding perforations in the other, substantially asand for the purposes set forth.

2. A radiator-section composed of two plates of sheet metal withcorresponding grooves or channels in their adjoining faces forming anendless tubular passage and provided on opposite sides with couplingsinserted in lateral openings into said passage and formed with angeswhich are folded over and embrace the edges of said openings on theinside and outside of the passage, one of said couplings beinginternally and the other externally screw-threaded, substantially as andfor the purposes set forth.

3. A radiator-section composed of two plates of sheet metal withcorresponding grooves or channels in their adjoining faces forming anendless tubular passage, said plates being joined together at the outerside of said passage by one being folded over the edge of the other andat the inner side where the plates come together by eyelets formed inone of the plates and inserted through and folded over the edges ofcorresponding Vperforations in the other, and provided on opposite sideswith couplings inserted in lateral openin gs into said passage andformed with flanges which are folded over and embrace the edges of saidopenings on the inside and outside of the passage, substantially as andfor the purposes set forth.

4. In a radiator, the combination of a number of sections each composedof two sheetmetal plates with corresponding grooves or channels in theiradjoining faces forming an endless tubular passage, and provided at ornear one end on opposite sides with male and female couplings insertedin lateral openings into said passage and connecting each section withthe adjacent section or sections, a rod passing through eyelets in saidsections, and

sleeves placed on said rod between the several sections and holding themin their proper relative positions, substantially as and for thepurposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
